How can a stick insect hide in plain sight?
A stick insect can look much like a twig. Its long, thin body and colors can match the branches around it. A hunter may look straight toward it and still miss it.

Staying still helps the insect blend with the background. Some stick insects also sway as they move, rather like a twig moving in a breeze. Shape, color and movement can work together.
The insect has not turned into wood. It is a living animal whose appearance makes it harder to pick out. A different background, or a hunter using other senses, can make the disguise less useful.
